Hey guys, I just picked up a 1947 Loadmaster that has the 216 and 4 speed.

I am looking for what I may be able to do not wind her up so tight cruising around, I don’t wanna go cruising down the highway but maybe easily get to 50 mph.

I’m just learning my way around these so not sure where to start if I should try to throw in a new gear or finding a retro 5 speed to replace the old 4 speed.
